This page reveals the full plot of Chapter 9 of Cross and Sampson. If you haven’t read that far yet, bookmark this analysis and come back after you finish the chapter.
Summary
The chapter opens with a piercing scream that sends John Sampson running out of a Panera into a street littered with broken vehicles, shattered glass, and wounded bystanders. He quickly realizes the sound is not a scream but a furious shout. An agitated woman in an ATF windbreaker is berating two DC firefighters who are hosing down the charred remains of an Audi. She demands they stop destroying her crime scene. A fire chief intervenes, and the hoses are shut off. FBI Special Agent Ned Mahoney introduces the woman as Anna Rizzo, an explosives enforcement officer with the ATF. Sampson recognizes her name: she is the investigator who cracked the Iowa grain‑tower bombings by finding a thumbprint on a tiny shard after twenty hours at an examination table.
Rizzo shifts immediately to the present. She asks Sampson for a status update. He reports that the Special Operations Division is canvassing for surveillance footage and interviewing witnesses. Mahoney adds that no threats or warnings preceded the blast, and no group has claimed responsibility. Rizzo claims ownership of the entire scene, particularly everything within two hundred feet of the crater. Noticing that a broken water main is still flooding the gutter, she phones the Water and Sewer Authority and threatens to arrest someone named Paul Baker for interfering with a federal investigation if the flow isn’t stopped within two minutes. Sampson offers to go knock on doors at the utility himself. Rizzo smiles and says they’ll work well together.
After the call, the three investigators survey the devastation. Rizzo shares an FBI profiling insight: bombers fall into disorganized asocial offenders, who build crude pipe bombs for a sense of power, and organized nonsocial offenders, who are highly intelligent, motivated by revenge or terror, and construct technically proficient devices. She concludes that the Washington, D.C., bomber is the latter—sophisticated, experienced, and unnervingly fastidious. Sampson agrees, noting that dedicated perpetrators rarely get sloppy.

Character Development
John Sampson – This chapter highlights Sampson’s quick instinct to help and his respect for domain expertise. He recognizes Rizzo’s name immediately, compliments her past work, and offers to handle a non‑forensic task (confronting the Water and Sewer Authority) so she can focus on the scene. His willingness to play a supporting role underscores his team‑first mindset.
Anna Rizzo – Rizzo is introduced as a forceful, no‑nonsense professional who does not suffer interference. Her aggressive protection of physical evidence, her blunt phone threat, and her refusal to accept luck as an explanation for her success paint her as relentless and detail‑oriented. Her quiet assessment of the bomber’s intelligence and dedication reveals a thoughtful tactician beneath the combative exterior.
Ned Mahoney – Mahoney continues to serve as a connector, smoothly introducing Rizzo and Sampson and providing context about the lack of a claim of responsibility. His brief appearance reinforces his role as the orchestrator of federal and local cooperation.
Themes, Symbols, or Motifs
Evidence as a living thing – The chapter treats the crime scene almost as a patient that must be protected from contamination. Rizzo’s fury over the fire hoses and her immediate move to stop the flooding water main symbolize the fragility of forensic evidence and the urgency of preserving it before it is lost.
Dedication versus luck – Rizzo’s backstory challenges the idea of a lucky break. Mahoney’s correction (“That’s not luck. That’s work.”) and Sampson’s later comment that dedicated bombers don’t get sloppy create a mirror between the investigator and the perpetrator: both are defined by obsessive commitment.
The organized offender – The bomber profile Rizzo sketches—highly intelligent, technically proficient, fastidious—serves as a motif for the antagonist the team faces, turning the abstract disaster into a personal adversary with a warped but coherent logic.
Why This Chapter Matters
Chapter 9 is the first extended introduction to Anna Rizzo, a character who will presumably be central to the investigation. Her expertise and aggressive personality immediately raise the stakes: the reader now has a forensic expert capable of interpreting the blast, and her profile of the bomber sets a chilling tone for the hunt. The chapter also establishes a dynamic where Sampson willingly defers to specialized knowledge, showing that effective teamwork across agencies is essential. Finally, Rizzo’s insistence on safeguarding the crime scene underscores a procedural realism that grounds the thriller in authentic law‑enforcement practices.
Study Questions & Answers
-
How does Anna Rizzo immediately demonstrate her authority at the crime scene?
She shouts at firefighters to stop hosing the wreckage, calls them “idiots,” and demands they preserve her evidence. She then tells the fire chief directly what the problem is, and when the water keeps flowing from a broken main, she phones the utility authority and threatens to arrest someone for obstruction of a federal investigation. Within minutes, she has asserted control over both the fire crew and municipal infrastructure. -
What contrast does Rizzo draw between the Iowa grain‑tower bomber and the D.C. bomber?
In Iowa, the bomber made a mistake—leaving a thumbprint on a fragment—that allowed Rizzo to catch him after exhaustive work. The D.C. bomber, however, shows no signs of sloppiness. Rizzo classifies him as an organized nonsocial offender: highly intelligent, technically skilled, and motivated by a complex internal logic. She calls him “fucking fastidious,” implying he will be far harder to catch. -
Why does Sampson offer to visit the Water and Sewer Authority, and what does his offer reveal about his character?
Sampson sees that Rizzo’s time is better spent examining the blast site, so he volunteers to handle the bureaucratic hassle of getting the water shut off. The gesture shows his instinct to remove obstacles for his colleagues, his comfort with a supporting role, and his respect for Rizzo’s forensic expertise. It also reinforces the theme of inter‑agency cooperation: a D.C. homicide detective is willing to play enforcer for an ATF officer because they share the same goal.
